et15. Are they a straight fit (if not, why)?
Spacers are illegal in belgium, so i would prefer not to use them.

16 x 9 all round, front and back?

Will fit okay on the back but they need at least a 3mm spacer on the front to clear the strut.

All round.
Does a KW V1 suspension change anything about this problem?

I don't think it does but not 100% sure on that.

Does the car have 51mm struts, 325?

It's a touring, so iirc it has 51mm.

Yep should be 51mm. It will be a tight fit, maybe you could try and see what it's like

With some luck, I can have a set really cheap. Worth a try.
Thanks.

Do all 16x9 rims need a spacer on the front? Or just the borbet's?

I would guess all do but every where manufacturer is different so can't really say without trying the wheel on.

Its not the 9" that gives the problems, its the ET15. On 45mm struts it wil rit. On 51mm it doesn't. As sad earlyer aboven You need spacers minimum 3mm.
I've got Borbet A's 9x16 Et15 on my Touring. With spacers. Now they go under my 316 4 doors without spacers.

Theres a guy over here in the US running 16x9 et15 Borbet type T's with no spacers on 51mm strut tubes. I think he ground the strut tube a little bit to fit them. Kinda sketchy but if you can't run spacers it's the only way other than swapping to 45mm struts up front.

I had borbet a's on my touring for a while. I had a blow out because the tyre was hitting the strut.... Not nice. Thye were 9j by the way

I can confirm that Borbet T's will fit without spacers.

9J all round.
